Geological units modelled

In total, 64 superficial and artificial geological units were modelled (including mass movement deposits). Table 1 lists the units in broad stratigraphic order together with the BGS stratigraphic lexicon code for each (see https://www.bgs.ac.uk/lexicon/) and lithology. Standard BGS map colours have been used for all superficial units in the model (Figure 2). These should be referred to when viewing images of the model in this report. Note that the Head and Clay-with-flints deposits are known to be polycyclic, and in the case of the latter, its formation is likely to have started as early as the Pliocene

Inferred' 'age LEXICON' 'CODE Full name Lithology
Holocene deposits and artificially modified ground slip Landslide deposits Mass movement deposits; variable composition, dependent on the nature of the upslope material
wgr Worked Ground Artificially lowered area, or void, through man-made excavation, e.g. a gravel pit
mgr Made Ground Artificially raised areas, variable composition
wmgr Worked & Made Ground Area of artificial cut and fill, e.g. a backfilled quarry, variable composition
ddgr Disturbed Ground Area of disturbance associated with surface or near-surface collapse
lsgr Landscaped Ground Extensively remodelled areas where it is difficult to delineate zones of Made, Worked or Disturbed Ground. Variable composition
peat Peat Humic deposits, consisting of wet dark brown partially decomposed vegetation
